Cleff, J. Epping, P. Gross, C. Fallnich] We present detailed investigations of a femtosecond green-pumped optical parametric oscillator (OPO) based on lithium triborate. As pump source, a frequency-doubled Yb-fiber laser-amplifier system is used. The OPO generates signal pulses tunable over a spectral range from 780 to 940nm and idler pulses tunable from 1630 to 1190nm. More than 250mW are generated in the signal beam and more than 300mW in the idler beam. Without dispersion compensation chirped signal pulses with a pulse duration between 100 and 250fs are measured. Using this system for coherent anti-Stokes Raman scattering spectroscopy, vibrational resonances between 1110 and 6760cm−1 can be excited. Due to the chirped pulses, a spectral resolution of 100cm−1 is achieved, which is 2.5 times higher compared to an excitation with time-bandwidth limited pulses. Springer-Verlag, 2011 Cleff C.
